I have all the old Dapol figures packed away somewhere. I have the TARDIS, too, but never got the interior with the control panel (which was made with only five sides instead of six, as the BBC never sent Dapol decent reference pix to work from). I've got both version of Davros, too (the rare two-armed, as well as the "corrected" one-armed).
Did they make toys from the new series? I'd love to have figures of Christopher Eccleston and Billie Piper!
EDIT: Well, I did a little research ... no Doctor #9 figures that I can see, but they do have a David Tennant figure!
